The traditional raw earth rammed earth wall has the unique color of raw earth around the world, and the unique rammed earth mechanism formed in the process of mechanical or manual compaction. Its unique and simple style is favored by architects. The most important architectural form. Later, it declined due to the production of concrete. In recent years, modern rammed earth walls have become popular again in Europe, America, Australia and other countries due to factors such as returning to nature, energy conservation and environmental protection, reshaping the characteristic traditional cultural symbols of various places.

Modern rammed earth walls can be divided into pure raw earth rammed earth walls and mixed rammed earth walls.
Pure raw soil rammed earth is a rammed earth wall made of complete raw soil as the base material and rammed with modern machinery and formwork technology.  

Mixed rammed soil is a mixed soil in which cement, lime and various additives are added to raw soil. Rammed earth walls built using mechanical and formwork techniques.  
Pure raw soil rammed earth walls are limited by the difficulty of obtaining large-scale soil that meets the requirements. Body surface sand and other issues. It is relatively difficult to adopt it on a large scale in modern buildings. It is more suitable for single-story or two-three-story buildings such as rural areas. The mixed rammed earth wall is more suitable for urban use due to the added cement and other reasons that increase the strength of the rammed earth and improve the performance of the rammed earth.

Shenzhen Simon United Building Materials Co., Ltd. is introducing mature wall decoration materials from Europe-- ---On the basis of thick-layer facing mortar, learn from the concrete formwork technology and pouring process in modern engineering construction. Colored rammed concrete obtained by improving and mixing rammed earth on the basis of facing mortar. Because Simon colored rammed concrete adopts concrete formwork and layered pouring ramming technology, it can make the same ramming mechanism as the raw earth rammed earth wall. In terms of color, Simon's mature finishing mortar color matching technology can meet the requirements of builders for wall color. Suitable for urban building use.

Two types of Simon colored rammed concrete walls:

1) Simon colored rammed concrete solid walls
Plant steel bars and support templates according to the design requirements, the thickness of the wall is 400-500mm, and use polystyrene board as the heat insulation layer in the middle. Fill the Simon colored rammed concrete that meets the design requirements in color and granularity layer by layer into the middle of the formwork, and tamp the wall with a pneumatic rammer. After the wall strength reaches the requirement, remove the formwork and clean the wall. A clear concrete protector can be applied to prevent carbonation of the concrete.  
The strength of the tamped wall cast by this process is not lower than C 20. The proportion of wall width and height that meets the requirements of modern architecture can be achieved.

Color:< ;br /> Simon colored rammed concrete is available in 10 standard raw earth colours. The color can also be adjusted according to the architect's design requirements.
Simon colored rammed concrete walls can be rammed by single-color rammed layered pouring and multi-color (2-5 kinds) layered pouring rammed.  
The use and maintenance of Simon colored rammed earth concrete.

The strength of Simon colored rammed concrete can reach the strength of concrete C20 and above, and it is resistant to rain erosion. The surface will not be sanded, and the color is firm and basically does not require special maintenance. It can be used as a partition wall and decorative wall of a building. In order to prevent the carbonization of the colored rammed concrete, a transparent concrete protective agent can be painted on the surface of the wall.
